This essay analyzes four visual sources that shed light on the relationship between gender and animal intimacy in interwar Britain. They are all photographs appeared print media, relate to production of wildlife films. The first is a montage six showing woman’s friendship with “strange savage beasts” London Zoo; second an advertisement for popular remedy; third shows director shooting zoo film;...

Long-time behavior is one of the most fundamental properties in dynamical systems. The limit behaviors flows on surfaces are captured by Poincaré-Bendixson theorem using ω-limit sets. This paper demonstrates that positive and negative long-time not independent. In fact, we show dependence between sets α-limit points surfaces, which partially generalizes theorem. Applying dependency result to so...

We initiate a systematic investigation of the abstract elementary classes that have amalgamation, satisfy tameness (a locality property for orbital types), and are stable (in terms of the number of orbital types) in some cardinal. Assuming the singular cardinal hypothesis (SCH), we prove a full characterization of the (high-enough) stability cardinals, and connect the stability spectrum with th...

We study sets and groups definable in tame expansions of ominimal structures. Let M̃ = ⟨M, P ⟩ be an expansion of an o-minimal Lstructure M by a dense set P . We impose three tameness conditions on M̃ and prove a cone decomposition theorem for definable sets and functions in the realm of the o-minimal semi-bounded structures. The proof involves induction on the notion of ‘large dimension’ for def...

In this paper it is established that all two-dimensional polynomial automorphisms over a regular ring R are stably tame. This results from the main theorem of this paper, which asserts that an automorphism in any dimension n is stably tame if said condition holds point-wise over SpecR. A key element in the proof is a theorem which yields the following corollary: Over an Artinian ring A all two-...

Whereas studies in comparative cognition normally invoke ecology and social organization to account for differences in social behaviour and cognition across species, dog–wolf differences have so far been explained mostly as a result of direct human selection for desirable traits (e.g., tameness, attention to humans, sociability). Yet, as will be reviewed in this paper, dogs and wolves also diff...

Domesticated animals tend to develop a coherent set of phenotypic traits. Tameness could be a central underlying factor driving this, and we therefore selected red junglefowl, ancestors of all domestic chickens, for high or low fear of humans during six generations. We measured basal metabolic rate (BMR), feed efficiency, boldness in a novel object (NO) test, corticosterone reactivity and basal...

We prove a partial generalization of Bonahon’s tameness result to surfaces inside irreducible 3–manifolds with hyperbolic fundamental group. Bonahon’s result states that geometrically infinite ends of freely indecomposable hyperbolic 3–manifolds are simply degenerate. It is easy to see that a geometrically infinite end gives rise to a sequence of curves on the corresponding surface whose geodes...
